Performance test results attached. The performance of grouping and deduplicating algorithms is improved by up to 23%.
53 identifies some issues with the
atomic_wait
/atomic_notify
interface. The signatures of the wait and notify methods from the sample implementation do not match those in the C++20 standard, and the fallback when the standard library already implements them uses aliases which do not permit type deduction. This fixes both of those issues.Some other compile issues with C++20 enabled have also been fixed, including some cases of aggregate initialization in
TestParallel
which are no longer valid, and the packed struct extension used insequence_base
, which wasn't applied widely enough.This patch also addresses #40 by changing the hashing function Parlay uses for integer types. This corrects the performance regression in the grouping and deduping algorithms observed post-PR #22.
